RE: IIIa Foil Project Sucess!

Note that the woofers are against the side wall, this makes up for the reduction in baffle size because they aren't next to the mid/tweeter panel. Also, phasing is important, they have to be a multiple of half a wavelength away at the crossover point and need their polarity flipped if they're at an odd multiple to avoid getting a suckout due to phase cancellation. Within this criterion, you want them as close as possible with an analog crossover. None of this matter with a digital crossover, since you can adjust delay and phase where you want it.
